Downloading music I got this mp3 without any info on how to operate. can you give me pointers on how to download music?

What kind of MP3 player do you use? If it's an iPod, just transfer music via iTunes or iTransfer tool.
How to Transfer Music to iPod without iTunes

MP3 players can only play music files in mp3 file format.
You can download mp3 music files from the Internet to your computer and then copy them to your MP3 player using the USB cable.
For your CD collection, you need to convert your CDs to mp3 music files onto your computer or download them from the Internet and then copy them to your MP3 player after you have connected the USB cable to the MP3 player and the computer.
You can do this using Windows Media player and Rip the CDs - Media Player will create a MP3 music file for each music track.

If you are downloading music with digital rights management (which sounds like what you are doing), you'll have to go through Windows Media Player (version 10 or better) to "synch" your music. Once Media Player recognizes your GPX, you'll drag the items you want copied over to the GPX and download them that way.

Then you can't get any songs. I know a good site that I get lots of FREE and LEGAL music without REGISTRATION. Try, www.mp3raid.com - a site that gives you free music without viruses trojan, spyware etc, and www.listentoyoutube.com where you get the mp3 music from a youtube video, whether it be a music video etc. None of these are harmful to your computer, and none of these need downloading they are browser based, and they require no registration or credit card details. You could also upload your own CDs onto your computer and then put them onto your mp3. I hope this helped.

try formatting the player

well i lost the disc i need help without paying for it.

You must convert to mp3 or acquire a DRM license
